Three-time Grammy winner Lizzo made a special performance on Tuesday, playing a 200-year-old crystal flute gifted to President James Madison. To the delight of thousands of fans at the Captol One Arena in Washington D.C, the pop star exclaimed “Thank you to the Library of Congress for preserving our history and making history freaking cool!" 

Earlier, Librarian of Congress Carla Hayden had pinged Lizzo on Twitter. The Library possessed the world's largest flute collection, Hayden posted temptingly, going on to describe a particular treasure.

Created by 18th century French craftsman Claude Laurent, the crystal flute presented to Madison on his second inauguration had been among the items Dolley Madison rescued from the White House in April 1814 as the British advanced on the capitol in the War of 1812, according to the Library.

"IM COMING CARLA! AND I'M PLAYIN THAT CRYSTAL FLUTE!!!!!" Tweeted Lizzo in response. 

"For your friendly national library, this was a perfect moment to show a new generation how we preserve the country's rich cultural heritage. The Library's vision is that all Americans are connected to our holdings. We want people to see them.," read a release.

So the priceless flute, with a full escort of security and Library experts remaining close by, was brought to the 20,000-seat Arena. 

Lizzo, whom the Guardian has proclaimed "the flute's brightest champion," was clearly thrilled and scared, she admitted to screaming fans, who cheered as Library curator Carol Lynn Ward-Bamford brought the flute to center stage.
